My DF-02 was delivered yesterday.
Unpacked it, put my warped/dished "Wolfmother" LP into the unit.
You can select 60, 90, 120 or 150 minutes heating time. the Wolfmother LP is about 150gm's, so I selected 90 minutes and closed the lid.
The LED display counts down, then automatically goes to 2 hours for cooling.
Took the LP out, put it back on the platter and guess what - no real difference - still warped - damm.
Put the LP back into the DF-02 and selected 2 hours and went to bed.
Got up this morning and put it on the platter - the LP is now nice and flat and plays fine.
So far so good and excellent to have the choice of how long to heat for. I'll report back after I have done 10 or so LP's.
cheers
